FAQ

FAQ

What is the difference between a WAF and a network firewall?

A network firewall controls traffic based on IPs and ports, while a WAF analyzes the content of HTTP/HTTPS traffic to block web attacks. Using both solutions together builds stronger security.

Does deploying a WAF affect website performance?

Modern WAFs minimize processing latency with optimized rulesets and hardware. Latency is generally 50 ms or less, which is hard for users to notice.

Can I use a WAF in a cloud environment?

Yes, it can integrate with major cloud environments such as AWS, Azure, and GCP, and can be deployed as a cloud-native WAF or as a proxy.
